lrSHBBTS-EHEBT l. fahr 6". ffoayson A pair, preferably the lower one, with a nozzle-socket d4, preferably of conical form, to receive the tapering end f of the molten-solder-discharge nozzle F, and thus admit the molten solder to the annular recess of the mold and to the rim of the canca i. One of the molds of each pair, preferably the upper one D, is furnished with a rim d5, which snuglyfits the Corresponding wall d" of the other mold D, and thus closes the annular solder-receiving recess of the molds and prevents, in connection with the can-cap, the escape of solder and confines the solder to the exposed portion ol' the can-cap rim adjacent to the solder-receiving annular recess d of the lower mold l). The upper mold 1) is preferably furnished with a recess d? and a rubber pad d8, having a projection d to close the vent-hole in the can-cap X, and thus cause the can-cap to adhere to the up )er mold or holder D by suction, the hofder D/ having passages r/l" therein connecting through a hose or tiexible connection E with a vacuum or exhaust chamber preferably on the carrier C.

The can-caps are automatically fed or delivered one by one to one of the molds l) D, preferably the upper one, by the feeder B, as the carrier brings each pair of molds in position for receiving the eanap. The can-cap feeder B is preferably hinged to the frame at B and its lower end vibrated, as required to press the lowermost cap therein against the suction-pad of the upper mold D', and thus automaticall \Y feed or deliver the cap thereto, l prefer to use air-suction instead of a magnet for causing the can-cap to adhere to the upper mold D', and I also )refer to so combine the feeder with the molds that the can-caps are delivered thereby to the upper mold instead of to the lower one upon which gravity would cause the can-cap to remain in position until the upper mold closes. The upper mold D of each pair is opened and closed against the lower mold by its stem D2 engaging a stationaryv cani G on the frame of the machine as the carrier rotates, a spring D3 surrounding the stent IP and bearing at its lower end against the bracket C2 on the carrier, serving to hold the upper mold normally retracted or open.

H is the molten-solder pot or vessel, the same having a solder-chamber i, a piston chamber or cylinder i, a solder-duct h2, leading from the lower end ot' the piston chamber or cylinder to the valve-chamber h3, with which the solder pot or vessel is also provided. The discharge-nozzle F is preferably made in a separate piece from the solder pot or vessel and secured thereto by boltsf. The tapering endjv on the nozzle F has a small discharge-orificefg, which is normally closed by the discharge-valve Fl engaging the valveseatfg. The valve-sterol"4 of the valve F is also furnished with a choker-valve F2, which is furnished l engages a valve-seatf5 at the inner end of the valve-chamber k3, which conununicates by a passage h with th'e molten solder in the pot or vessel H. The molten-solder pot or vessel H also has a piston or plunger li', which operates to force the molten solder through the valve-chamber and dischargenozzle and into the annular 'recess of the molds when the discharge-valve is open, and

the choker-Valve closes the return})assagev between the valve-chamber and solder-chamber of the solder-pot. The solder pot or vessel H is also furnished with a heating-chainber H2 for heating and keeping molten the solder `in the solder-pot7 valve-chamber, and discharge-nozzle. The heaters in t'he heating-chamber are preferably gas-jets ll,

To operate the discharge-nozzle or move it into and out of contact with the mold, l )referabl y mount it rigidly instead of movabfy on the solder pot or vessel and mount the solder pot` or vessel itself movably upon the frame of the machine, as this obviates the necessity for any movable or stufiing-box connection between the discharge-nozzle and solder-pot and somewhat simplifies the machine. The solder-pot is for this reason preferably provided with wheels or rollers H4, which travel on ways A on the frame. The wheels or rollers IIA1 are preferably journaled on eccentrics H, fixed on shafts H", which shafts may be ad usted by turning them more or less and then holding them by screws H7 to var) the height of the discharge-nozzle as required to accommodate caps of different diameters. Adjusting-screws H serve to ad'ust the pi i tion of the solder-pot horizontally in respect to the carrier. The solder-pot and dischargenozzle are separated as required by means of a cam K on the driving-shaft` K through the connecting-lever K2 K3 and link K, the link being provided with a turnbuckle K5 for adjusting the throw or reciprocating movement of the solder-pot and discharge-nozzle.

The carrier C preferably has an upright hollow shaft C13, surrounding the upright stationary stem A2, which is connected to and forms a part of the frame, and thc carrier is intermittently rotated as required to bring each pair of can-cap holding and receiving molds in turn into position for registry with the solder-discharge nozzle and with the cancap feeder B by a Geneva stop mechanism Cf* C* CF', the rotating arm C5 carrying the pin C4, which engages the slots C*l of the disk C3, the arm C5 being on a shaft CT, having gear CS, meshing with gear C9 on the shaft Cl", which has agear C, meshing with a gear C12 on the cam-shaft or driving-shaft K.

The piston or plunger H of the solder-pot is reciprocated as required by a cam hi on the cam-shaft K through the connecting-link 71. and levers k7 k7. A spring la, surrounding the stem h of the piston H serves to retract the piston. The piston H, has a solder duct IOO ISO
